Noise emissions (“volume”) and fan speeds
The measured fan curve of the MSI GeForce RTX 5080 EXPERT shows a thermally stable and extremely even control behavior. After a start-up phase of just under three minutes, the fan reaches a constant speed of around 1410 rpm, at which the GPU temperature also stabilizes at around 67 °C. It is noticeable that the speed curve shows no visible fluctuations or cyclical regulation, which indicates an optimized PWM control without hysteresis or aggressive tuning. The flat curve shape above 1200 rpm confirms a prioritized design for even noise development and not for maximum cooling performance at low temperatures.
The MP3 recording, which was made directly in a low-noise measuring chamber, illustrates the balanced sound of the rotors used. The 11.5 cm fan uses nine asymmetrically profiled blades with a relatively steep run-up line and blade ends pulled far back, which minimizes turbulence in the transition to the housing wall. The bearing seems to be based on a liquid-damped sliding solution, as no metallic whirring or bearing knocking can be detected either during start-up or in stationary operation. Subjectively, the sound is soft, round and without tonal peaks. The basic characteristic remains low and frequent throughout, which means that the perceived loudness is significantly lower than the SPL value alone would suggest. In stationary operation, a sonorous air noise is produced rather than a perceptible noise with interference components.
The spectrogram and the associated RTA range in the Smaart evaluation provide objective evidence of this. The distribution of the acoustic level is strongly concentrated in the interval between 125 Hz and 2.5 kHz, with a local maximum around 130 Hz. The fan is the dominant noise source there, with the spectrum being broadband and without sharp resonance peaks. Only between 3.8 and 4.3 kHz can a slight increase be detected, which is noticeable in the MP3 as a discrete coil beep. However, it is acoustically harmless. Above 8 kHz, the acoustic signal lies within the range of the measurement chamber’s background noise. This proves that no high-frequency noise from the motor or the PWM control is transmitted to the fan.
Subjectively, the noise pattern of the MSI RTX 5080 EXPERT can be rated as quiet, unobtrusive and even. There are no annoying high-frequency artifacts or low-frequency droning, as can occur with some asymmetrically running axial fans. The cooling remains largely in the background acoustically and does not produce a characteristic “gaming card sound”. This makes the card particularly interesting for semi-passive or quiet systems in which constant, low-frequency noise is less noticeable than dynamic whistling or rattling. The MSI GeForce RTX 5080 EXPERT is therefore audibly lower than many other cards in the same performance class.
